7.3.1 Isolation Amplifier

The ISO124 is a precision analog isolation amplifier. The input signal is transmitted digitally across a high-voltage differential capacitive barrier. With digital modulation, the barrier characteristics do affect signal integrity, resulting in excellent reliability and high-frequency transient immunity.
